METHOD FOR MANUFACTURING DISPERSION OF QUINOLINE DERIVATIVE

A method for manufacturing a dispersion of a quinoline derivative that is dispersed at a high concentration and has a small particle size. The method includes the steps of preparing a solution by dissolving an N-arylanthranilic acid derivative in an organosulfonic acid, heating the solution and obtaining a reaction liquid in which a quinoline derivative has been produced by a condensation ring-closing reaction, and obtaining a dispersion of the quinoline derivative by mixing the reaction liquid with an aqueous solution. The step of mixing the reaction liquid with an aqueous solution may be performed in a mixing field having a micro-channel.

PROCESS FOR THE PREPARATION OF ORGANIC PIGMENTS

The present invention relates to advantageous processes for the manufacture of organic pigments and their precursors. The invention particularly relates to reactions carried out in an "All In One Reactor" (Draiswerke GmbH, Germany), a kneader like the TurbuKneader of the same company, a paddle dryer like the Turbudry of the same company or a related system and thereby submitting the reaction mixtures to enhanced driving power as expressed by a Froude number>1, the reaction mixture being caused to react in high concentrations at elevated temperature.
